Mars, eh? We sent a little RC car up there and saw that it is indeed rocky and orange.

Is there more we need to do?

militarize, colonize and explore/develop potential resources for trade, business and the defense and expansion of human liberties and the dreams of mankind.... for starters.

some folks are content to stay on the land, fearing travel in the sea and air.
some folks are not.
explorers, pioneers and settlers... are ALWAYS looking for opportunities to push beyond the current envelope's limitations.
